# ── Adaptive Alert Triage — Optimised Dockerfile ─────────────────────────────
#
# Key change vs previous version:
#   - Installs ONLY core deps from pyproject.toml (no torch / stable-baselines3)
#   - torch + stable-baselines3 are in the [train] optional group — NOT here
#   - Build time: ~60-90s  (was ~2200s pulling 2GB of PyTorch)
#
# Build:
#   docker build -t adaptive-alert-triage:latest .
#
#
# Run server:
#   docker run -p 7860:7860 adaptive-alert-triage:latest
#
# Run inference baseline:
#   docker run --rm \
#     -e API_BASE_URL="https://api.openai.com/v1" \
#     -e MODEL_NAME="gpt-4o-mini" \
#     -e HF_TOKEN="hf_..." \
#     adaptive-alert-triage:latest \
#     python inference.py --n 3
#
# Environment variables (set at runtime, not here):
#   API_BASE_URL  — LLM endpoint  (default: https://api.openai.com/v1)
#   MODEL_NAME    — LLM model name (default: gpt-4o-mini)
#   HF_TOKEN      — Hugging Face / OpenAI API key
#   PORT          — Server port   (default: 7860)
